In the opposite direction of the classrooms is an abandoned room at the end of the hall to the left. The empty room has a ladder in the right corner in the room. Go up through the trap door you will find and enclosed garden. This large room is filled with plants and flowers. In the center is a fountain and there are benches spread out in the garden. Toward the windows is a blank spot so that you can lay out on the ground and look at the stars.
